BYRON A. BROOKS, OF BROOKLYN, NEW YORK.

.SPECIFICATION formingpart of Letters Patent No. 748,578, dated January'5, 1904.

Application filed January 24, 1900. Serial No. 2.574:- (No model.)

.the following is a full, clear, and exact description.

Myinvention consists of certain novel parts and combinations of'parts, the several features of which will be separately and specifically pointed out in the claims concluding this specification.

The following description, taken in connection with the accompanying d rawings, will en able persons skilled in the art to which my invention relates to understand its nature and to practice it in the form in which I have preferred to embodyit; but it will be understood that my invention is not limited to the precise devices or combinations of devices herein illustrated and described, as various modifications may be made without departing from the spirit of my invention and without exceeding the scope of the claims concluding this specification.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a front elevation of my device. Fig. 2 is a side elevation of my device. Fig. 3 is a sectional elevation of the mechanism used for feeding the type receivers or carriers. Fig. 4 is an elevation, partially in section, of the mechanism shown in Fig. 3, but taken at right angles thereto. Fig. 5 is an elevation of the same mechanism as shown in Fig. 3 with the parts in difierent positions. Fig. 6 is a sectional elevation through the same mechanism, taken at right angles to Fig. 5. Figs. 7and 8 are elevations showing the mechanism by which the space occupied by each type is measured. Fig. 9 is a diagrammatic view showing the electrical connections by which said type-measuring mechanisms are controlled. Fig. 10 is a side elevation of one of the sprocket-wheels over which the type-carrier passes and said typecarrier, together with the mechanism for properly placing the typein the carrier. Fig.

11 is a plan View of the same mechanism. Fig. 12 is a plan view of the mechanism for operating and controlling the type-measuring device. Fig. 13 isa plan and partial section of the threaded bolt by which the measuring of the space occupied by the type is accomplished. Fig. 14 is a side elevation and partial section of the mechanism by which the space-casting molds are operated. Figs. 15 and 16 are similar views showing the parts in diiferent positions. Fig.17isa front elevation of one of the sprocket-wheels, a'portion of the type-carrier,aud thetubes by which the spaces are inserted in the carrier. Figs. 18 and 19 are sectional elevations showing the mechanism for operating the type-casting device. Fig. 20 is a side elevation showing the typereservoir and one end of the type-delivering tube in section and the mechanism for operating the type-casting devices. Figs. 21 and 22 are perspective'views showing in detail the construction of-one of the links in the typecarrier. Fig. 23 is a front elevation of that portion of the machine containing the spacecasting and adjusting or justifying mechanisms. Fig. 24 is a plan of the space-molds and the justifying mechanism. Fig. 25 is a perspective view showing in detail one of the bars forming the space-mold and one of the justifying wedges or bars which are operated in connection therewith. Fig. 26 is a sectional side elevation of the mechanism for inserting the leads between the lines of type. Fig. 27 is a plan view showing the mechanism for transferring the line of type from the carrier to the galley. Fig. 28 is a detail of a portion ofthis mechanism, illustrating the operation of the switch at the point of trans ference from the carrier to the guide leading to the galley. Fig. 29 is a perspective view showing the mechanism used in transferring the line oftype from the carrier to the said guide. Fig. 30 is a perspective view showing in detail the switch, which lies at one side of said guide, and Figs. 31,32, 33, 34, 35, and 36 illustrate diagrammatically the various steps in theformation of a line of type and its transference to the galley.

The machine illustrated in the above drawings is designed to cast the various types required separately from each other, to assemble them in words and lines, and automatic-
